Detailed Description

template<class T>
class casacore::ImageConcat< T >

Concatenates images along a specified axis.

Intended use:

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

Etymology

This is a class designed to concatenate images along a specified axis

Synopsis

This is a class designed to concatenate images along a specified axis. This means you can join them together. E.g., join images of shape [10,20,30] and [10,20,40] into a lattice of shape [10,20,70].

The ImageConcat object does not copy the input images, it just references them. You can use the Lattice<T>::copyData(Lattice<T>) function to fill an output image with the concatenated input images

If you use the putSlice function, be aware that it will change the underlying images if they are writable.

You can also concatenate a lattice to an image.

Example

 IPosition shape(2, 10, 20);
 PagedImage<Float> im1(shape, CoordinateUtil::defaultCoords2D(),
 "tImageConcat_tmp1.img");
 im1.set(1.0);
 PagedImage<Float> im2(shape, CoordinateUtil::defaultCoords2D(),
 "tImageConcat_tmp2.img");
 im2.set(2.0);
 
// Make concatenator for axis 0
 
 ImageConcat<Float> concat(0);
 
// Relax coordinate constraints
 
 concat.setImage(im1, True);
 concat.setImage(im2, True);
 
// Make output image  and mask (if required, which it will be in this case)
 
 PagedImage<Float> im3(concat.shape(), CoordinateUtil::defaultCoords2D(),
 "tImageConcat_tmp3.img");
 
// Copy to output
 
 im3.copyData(concat);

See tImageConcat.cc for more examples.

Motivation

Image concatentation is a useful enduser requirement.

To Do

Offer the ability to increase the dimensionality of the output image

virtual Bool casacore::ImageConcat< T >::doGetMaskSlice	(	Array< Bool > &	buffer,

Reimplemented from casacore::LatticeBase.

template<class T>

void casacore::ImageConcat< T >::setCoordinates ( )

private

Updates the CoordinateSystem in the ImageConcat image.

The first lattice must be an image. The first lattice is contiguous by definition. The Coordinate System for the first image must be set before calling this function. For the first image, this function just sets up worldValues and pixelValues

template<class T>

void casacore::ImageConcat< T >::setImage	(	ImageInterface< T > &	image,
		Bool	relax
	)

Sets a new image into the list to be concatenated.

If relax is False, throws an exception if the images are not contiguous along the concatenation axis. If relax is True, it will create a non-regular TabularCoordinate for non-contiguous images if the coordinates are monotonic. Otherwise, it just uses the coordinates of the image

template<class T>

virtual Bool casacore::ImageConcat< T >::setImageInfo ( const ImageInfo & info )
